Anonymous objects: Temporary objects are usually released when they are constructed (special case, return value optimization)1. Return value optimization: If the anonymous object returned by the function returns with a new object of the same type,

First, the concept of enumerationsEnumerations are a basic data type in the C language, not a constructed type, which can be used to declare a set of constants. When a variable has several fixed possible values, the variable can be defined as an

Array:Array must specify its size when initializing the objectAbstract class, cannot constructor instantiate an array (for example: array arr = new array[] error)However, it is possible to initialize an array class array arr = new int[3]{1,2,3};You

Traditional collection operationsIn the absence of generics, we use Ayylist to manipulate the collection, which can hold any type of data, but eventually it is converted to object storage, and if the incoming data is a value type, you need to
